A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml. Recovery studies were performed by adding known amounts of methyl and ethyl alcohols to blood, lung and liver within the range 80–90%. The reproducibility of the results was always >90%. The quantitative distribution of methyl alcohol in postmortem body tissues and fluids has been reported in three cases of poisoning. 相似文献

The EPA implements its policy of exhaust emission control by setting standards specified in terms of grams of pollutants per mile traveled. As a result, the tax must first restrain the vehicle miles traveled (VMT) if it is to have an impact on emission at all. EPA's choice of miles traveled as the medium through which its policy of pollution control must run is unfortunate, because travel is an activity that people resist giving up. This is reflected in a low long-run price elasticity of travel demand. Consequently, it takes substantial increases in the gasoline tax to make an impact on long-run travel demand. Simulation results show that under an alternative policy option, where EPA's standards are specified in terms of grams of pollutant per gallon of fuel burned, the same long-run reduction in exhaust emissions achievable today can be achieved (at an even higher level of confidence) with less than one-tenth of the increase in gasoline price required under the existing policy regime. 相似文献

In this essay I examine the criminal defense file. I argue that being a largely neglected “object” of the legal field, upon
a close examination, the file discloses its intriguing materiality as what is predicated on the structure of the fold that
allows for the objective, virtual, and narrative spheres to overlap in a specific act-object, which, with Gilles Deleuze,
I call objectile. A subsequent phenomenological analysis of the legal file as objectile shows how its constitutive features help the attorney
shape ordinary matters into plentiful matters, turning the file into a locally designed sign system. Once exposed, this system
reveals its relations to the legal system at large, with individual activities, institutional practices, and legal procedures
all being a part of a complex manifold that is law. 相似文献

This article explores the reasons for the introduction of anticorruption agencies of a specific type in Eastern Europe. It
is argued that one of the important functions of these agencies—which are stronger on information gathering, coordination
and strategy rather than on investigation of concrete cases—is to give to the government some leverage over the anticorruption
discourse. Presenting the anticorruption commissions and agencies as (discourse-controlling) instruments gives an answer to
the troubling question why governing parties are at all interested in the introduction of such bodies. Apart from instrumentalization in political discourse, anticorruption
bodies in Eastern Europe have had other effects as well. As shown in the Baltic case, institutional engineering provides for
a brief window of opportunity during which political forces committed to integrity could gain the upper hand. The problem
in Eastern Europe, however, is not the lack of such windows of opportunities—it is more the lack of really committed political
forces capable of continuous and consistent anticorruption effort. 相似文献

This paper discusses empirical findings and theories about prison higher education and recidivism. The research designs of
available evaluations of prison higher education are discussed. Their results in regard to arrest and return to prison after
release are presented in tables and figures. Both opportunity theory and moral development theory have been used to justify
such prison programs as crime prevention measures. A critical examination of the actual findings of the evaluations carried
out up to now suggests that prison higher education may have had only a slight impact on recidivism. One could, therefore,
doubt the value of opportunity theory and moral development theory to justify prison higher education as a crime control measure.
However, the methods used in the evaluations of this program have been generally weak. Thus, there is a continuing need to
carry out well-designed research on this question. The findings of follow-up studies of prison higher education have significance
for issues of correctional education policy as well as criminological theory. 相似文献

Teaching Students How to Use Emotions as They Negotiate 总被引:1,自引:0,他引:1
Daniel L. Shapiro 《Negotiation Journal》2006,22(1):105-109
Given that emotions are inescapable and complex, how do you teach students how to deal with them? This article offers instuctors a practical approach. It suggests that instructors and students turn their attention away from emotions and toward a more limited set of core emotional concerns that stimulate many emotions. The article describes ways to teach students how to use these core concerns as tools to understand the emotional terrain and to stimulate helpful emotions. 相似文献

Although law enforcement agencies across the nation have assumed part of the responsibility in the fight against terrorism, significant confusion exists as to the role of local law enforcement. While some agencies have taken steps towards terrorism prevention, little data has been collected on which agencies have taken the greatest steps, how those agencies have changed, and how other agencies should direct their activity. This case study of law enforcement census data from a single state considered variations in terrorism preparedness and predictors of preparedness. Agency size, presence of funding, and other variables significantly predict levels of terrorism preparedness. Important policy implications such as the distribution of funding and which agencies should be working towards terrorism preparedness are discussed. 相似文献
